I know this might sound pedantic but I will try to write with love. 90% of the world population buy groceries weekly or more often. Many European countries buy fresh food on the daily. Yes, from the grocery downstairs, or across the road. Car centric urban design fucked you up. It's built for the car, not for human beings. Your perception and expectations are completely out of wack with normal human existence.

For example, Costco style mega stores are not a thing in almost all of the world. No, no one needs a 3 year supply of mustard for a family of 4. Most businesses don't need a heavy duty truck, why would a middle class family need one just to get to the school and office. You don't need a 4x4 for the two trips a year you take to the mountains, on an asphalt road.

It's all bizarre, it is all out of proportion. But it is not a personal failure, oil corporations and car manufacturers created this weird mar on the planet that is suburban sprawl and car dependent infrastructure. We just live with the consequences.

I wouldn't ask my 9YO on a bike at 7:30 am on winter to go to school everyday

Why not? In a lot of the world that's pretty normal.

When I was a kid I walked 30-40 minutes to and from school in the winter. I would have preferred to bike, but they didn't clear the bike lanes. In places in Europe they make plowing the bike lanes a priority, so everybody can count on being able to commute by bike.

The place we go to the most is on the other side of mountains 3 hours away by car.

You shouldn't have to rely on a car to get somewhere that's that far away. It's more reasonable to take a train to get that kind of distance.

Groceries would have to be more regular. I currently fill the car and go like once a month or month and a half

Do you not like fresh food? Do you ever eat fruit or vegetables? Or meat that hasn't been frozen?

You can just take some other transportation for long trips.
